A feature such as Charles describes is useful, and has already been defined for DAISY (ANSI/NISO Z39.86). An important additional requirement is a reliable way to escape out of the local mode--either forward beyond the structure, or back to something before it. It must be easy to "go local" or "stay global." PS: If memory serves, DAISY speaks of these as "escapable" structures.

Which might be the same as your idea. But perhaps I need to think harder. In the meantime I'll go back to some of the teams who produce these things at Yandex - they might have futher ideas. > > cheers > > -- > Charles McCathie Nevile - web standards - CTO Office, Yandex > chaals@yandex-team.ru - - - Find more at http://yandex.com -- Janina Sajka, Phone: +1.443.300.2200 sip:janina@asterisk.rednote.net Email: janina@rednote.net Linux Foundation Fellow Executive Chair, Accessibility Workgroup: http://a11y.org The World Wide Web Consortium (W3C), Web Accessibility Initiative (WAI) Chair, Protocols & Formats http://www.w3.org/wai/pf Indie UI http://www.w3.org/WAI/IndieUI/
